Browning, kimber, and savage make 280 AI. The savages have adjustable LOP that may benefit a gun used by 2 shooters. I have an xbolt in 308 that shoots fantastic.
A new barrel for the 700 that doesn’t shoot well is an intriguing option too.
This thread makes me feel like a wuss hunting where I do. Red fox is our greatest threat.
If I were charged by a bear I would want a hell of a lot of ammo. The xd with 17 rounds of 10mm and good sights would be my first option
